Be it known that 1, Joint? F. Fnrrz, a subject of the King of Sweden, who havd declared my intention to become a citizen of the United States, residing at Portland, in the county of ll/lultnomah and State of (lregon, have invented a new and useful Draining Apparatus for 'lunnels, &c., of which the following is a specification.

.My invention relates to pumping ma-' chinery for the removal of water from tunnels, mines and ditches, especially while the are under construction he object is to provide a cheap, sim le and economically operated apparatus or said purposes.

en a tunnel is being constructed there is almost invariably the diihculty encountered that springs or other water will flow into the tunnel or excavation and must be removed-by pumping, for wh'ch steam or other engines are then employed. In my experience, however, I have found that usually some stream or creek of water can be found not far from the work and utilized as motive power to operate the ump, especially it a special motor for ut' ring a low water pressure is constructed and the right kind of: water ining pipes and. valves are constructed for the purpose. My invention therefore comprises these means, as will pently be explained. p

In the accompanyin drawing;

Fire 1 is a side e evation of my apparatus about as near'asit can be represenmd in a single view. Fig; 2 is a lontudinal vertical section of one of the swivel oints 63- of the exhaust pipe of the engine. Fig. 3 is an elevation of the left hand end of the main structure shown in Fig. l. Fir. lis a face view of either one of the radia arms l8, l8" and 118 in Fi 1. Fig. 5 is a side dill plate, pistons 6 in the cylinders and provided with piston ma 7 moving crossheads 8 along guides 9 on the frame 3* holding the hearings or journal boxes 3. From said cross-heads .extend connecting rods 10, by which'cranks 11 of the engine shaft 12' are operated. Said cranks are arranged in opposite radial directions and the shaft is provided with an eficient flywheel 13 for carrying the cranks over their highest and lowest points. The shaft is also provided at one end with apulley i l for the transmission or" power to other machinery (not shown). Une spoke in the pulley is provided with a slot 15 (see Fig. 5), any part of which may be occupied by a cran pin 16 which is movably secured in a slot ill, (see Fig. 4) in a radial arm 18 fixed on a short pump shaft 19, which is thus rotated by the pulley said shaft is thus journaled in the bearing 4: oil the frame part 49 and provided at its oliter end with an-' other radial arm 18*, havinga slot 17 in 20, 20 may thus be altered to suit the available power of the engine.

Operated by the rods 20, 20 are two pistons 22 in pum it can not flow back into the tunnel.

The pipe 25 is extended into the tunnel and provided with several .branches 25,

25", 25, one branch for each pool or pit in' which the water is gathered. in the drawthe branch 25 represents any of the ot er branches by being shown as extending into the water 29, and is provided with a valve 30, operated by a lever 31 pivoted at 32 and provided with lever closes the val e and thus prevents air pg. in through he valve and break the c linders 23, which draw water through t e ranches 24 of a pipe 25 and discharge it from spouts 26 into a race 2'? which leads it to some place from'which a float 33, so that whenever the water is pumped away so that the float falls down ,to a certain point, its

suction in thepipe 25 which may yet be needed todraw water from other water pockets along the pipe line.

The water that operates the engine is carried f QU! the highest point obtainableldh or necessary through a pipe 34 into a cylindrical chamber 35 in which a two-headed slide valve 36,- 36" is fixed on a valve rod 37, and controls the intake and outlet ports ,38 in the lower ends of the cylinders 5. The

- 47 to base 2 and has its arm 45 provided with a pin 48 from which a spring 49 extends to a pin 50 in a frame post 51. The

other arm 46 of the lever has its end 52.

forked (see Fig. 6) so as to straddle the vertical rod 53, which is guided to slide in bearings 54, 55; the upper end of the rod is jointed at 56 to a connecting rod 57, which is operated by a pin 58, that is adjustable to any point in the slotted arm 18 on the en ine shaft.

hdjustably secured by set screws on the rod 53 are two collars, 59 and 60, which by means of intermediate compression coil springs, 61 62, on the rod act on the lever 46 to throw it alternately upward and downward.

Secured to the end of the slide chamber 35 by swivel joints 63 (see Fig. '2) are branches 64 of a water exhaust or discharge plpe 65, which has its free end submerged in water 66 in a tank 67, or a water pool in the ground will serve the same purpose, namely to revent air from getting into the p pe branc es and thevalve chamber. It w1ll be understood that where the conditions permit it the pipe should be made as long as possible and directed downwardl so as to create suction which helps to pul the pistons of the engine downward after the water has driven each of them in its turn upward.

In further describing the operation it will be understood that in this as in all water engines the slide valve must move quickly and then rest while each cylinder is alter-,

nately one filled and the other emptied. To accomplish this the spring 49 tends at all times to throw the lever arm 45 and thereby the valve rod 37 in one direction or the other and to hold the rod with one of the cushions 40 against one of the stufiing boxes 39, just as soon as the sprin is swung by the arm 45 to either side of t e fulcrum 47; and the bringing of. the arm to and slightly beyond its plumb down positionis also accomplished quickly by the ex ansion of each spring 61, 62, after it has een compressed by the collar 59 or 60, as the case may be. Experiments have demonstrated that where the fall of the Water is so limited that it is impractical to use a turbine or other water- 68 wheel this form of engine can be run by such fall and do the necema pumping, and that at a comparatively light cost of production and maintenance of the device.
